Black Cat Systems’ 22 Meter Band Part 15 CW Beacon Kit

Many thanks to SWLing Post contributor, Robert Gulley (AK3Q), who notes that Black Cat Systems has developed a simple 22 meter beacon kit. The price is $20 shipped! A few details:

The kit includes the PCB and components, including a custom programmed microcontroller that will continuously transmit the ID / callsign of your choice, up to 8 characters, at about 13 wpm.

Small size – just 2 7/8 by 1 1/2 inches. Easy to build, just a few components, all through hole, no surface mount.

When ordering you note your callsign/ID to send and it will be pre-programmed.

Black Cat Systems has all kit details including full instructions on their website.

If you like the idea of building a beacon, you must also check out the beacon Dave (AA7EE) built recently–a true work of art!

Yaesu FT-818 details emerge (and beware of the fake “leaked” photo!)

I’ve been following news about the Yaesu FT-818: the next iteration of the venerable Yaesu FT-817ND QRP general coverage transceiver.

The FT-817 series has been on the market for nearly two decades. I remember purchasing one of the first production models when I lived in the UK in 2001.

It was a revolutionary radio at the time.

It was exceptionally suited for portable use, sporting an internal battery pack, on-board keyer, had all mode/all band capability and antenna ports on the front faceplate and rear. It was the most compact full-featured transceiver on the market. All this for about $670 US.

In 2004, Yaesu made upgrades and launched the model FT-817(N)D. In no small way, I’m sure this little radio has been a cash cow for Yaesu. It’s had an exceptionally long market run and has been the only QRP transceiver in the Yaesu product line for decades.

Recently, Yaesu released specifications and retail pricing of the FT-818.  But before we go any further…

Don’t believe the fake prototype photos

It seems like every time a new amateur radio transceiver is announced, someone quickly assembles a “leaked” prototype image and publishes it on the web. Here’s the one someone pieced together for the Yaesu FT-818:

Click to enlarge (and see obvious Photoshop chop job)

To be crystal clear: this is not a leaked photo of the Yaesu FT-818. It’s (frankly) a terrible Photoshop job–someone playing with cutting, pasting and resizing bits from other transceivers.

I fully suspect the new FT-818 will not be a dramatic departure from the FT-817 in terms of styling and design. Perhaps it’ll be nearly identical. In fact, radio retailers have been posting the following image on their FT-818 ordering page:

This may simply be a placeholder, or it may be that all of the upgrades are internal and the ‘818 form factor will be identical to the ‘817.

Enough said…

What we do know about the Yaesu FT-818

Rumors of an FT-818 have been floating around the ham radio community for years. No surprise given the extraordinarily long run of the ‘817 series!

We do have concrete details now since ham radio retailers have been given features, specifications and availability dates. It appears the upgrades are iterative–this is not a dramatically re-designed rig.

Here’s what Yaesu has released (I took this from GigaParts, but retailers are posting variations of the same announcement):

Yaesu FT-818 6W HF/VHF/UHF All-Mode Portable Transceiver

The new Yaesu FT-818 incorporates all of the basic and attractive features of the ever-popular FT-817ND while providing upgrades desired by many existing owners.

The FT-818 provides 6W of solid output power with an external DC power source. The supplied Ni-MH battery pack (SBR-32MH) has been upgraded to now provide larger battery capacity – 9.6v/ 1900mAh. The recent launch of several new satellites is a certain indicator that the large global community of satellite enthusiast are going to be very delighted to learn that the FT-818 includes a Built-in TCXO-9 oscillator that gives the FT-818 fantastic frequency stability (±0.5ppm).

The FT-818 includes all the useful functions that are included in the FT-817ND: Dual VFOs; Split-Frequency operation; IF Shift; Clarifier “R.I.T”; IF Noise Blanker; RF Gain and Squelch control; IPO (Intercept Point Optimization); AM Aircraft reception; AM and FM Broadcast reception; VOX; Built-in Electronic Keyer; Adjustable CW Pitch; Automatic Repeater Shift (ARS); Built-in CTCSS Encoder/ Decoders; 208 memory channels with 10 memory groups; two antenna connectors; Automatic Power-Off (APO) and Time-Out-Timer(TOT) functions; and so on.

CommRadio CTX-10 approved by FCC

The CommRadio CTX-10

Many thanks to SWLing Post contributor, R. Lewis (KF5GV), who writes:

Just noticed on Universal Radio web page the Comm Radio CTX-10 has been approved by the FCC. They are accepting pre-orders on Dec 1. No indication of pricing but hope they announce it soon.

Thanks for the tip!

I’m looking forward to checking out the CommRadio CTX-10. For one thing, it’s in one of my favorite radio categories: portable general coverage QRP transceivers!

Since the CTX-10 receiver is likely an iteration of the excellent CommRadio CR1 series, I expect it’ll perform well on the broadcast bands as well as the ham bands. I look forward to reviewing the CTX-10.
